All I have done, is GAZ shocks/struts. I threw in an H&R front sway when that's all you could do. I have a rear sway waiting to throw in, but I have to put the stock front one back in in order to do so as I'm still in HS for the remainder of the season. But I have been kinda putting that off. After the results of the last two weeks, I might be more motivated to do so. I'm running OZ Ultraleggera wheels (about 15.5 lbs each), which require machining 1 mm off the hub face to be HS legal. 225/40 Hoosier A6's mounted on them. And I just threw in an all aluminum Top Speed cat back exhaust to between the NT and Pro, mainly to shed weight. A K&N drop in filter, and that's pretty much it.
